What makes the Auras CTC-868 heatsink stand out is that it's split into thirds, with the two outer sections holding the integrated fans. A slip connection at the base of the CTC-868 allows each outer third of the heatsink to pivot on the connecting heatpipe 20 degrees, in the process noise is slightly reduced and the exhaust airflow can be directed down towards the motherboard.http://www.frostytech.com/articlevie...articleID=2261
